STOVE-BOARD.

SPECIFICATION forming part of Letters Patent No. 230,002, dated July 13, 1880.

Application filed April 26, 1880.

stove-boards so constructed that they will not be twisted, warped, or drawn out of shape in shipping, selling, or in use, and will thus lie level upon the floor.

The invention consists in constructing a stove-board made with a bead and ahem, and having the lower ply of the hem corrugated and its edge turned up against the plate within the cavity of the bead, and the veneer cemented to the lower side of the middle part of the plate, as will be hereinafter fully described.

A represents a plate of zinc of any desired size. Around the plate A, at a little distance from its edge, is formed a bead, B. The edge of the plate A is turned under upon itself, or hemmed, and the under ply, G, of the hem D is corrugated, as shown in Fig. 2, andits edge is turned up against the plate -A in the cavity of the bead B. The corrugation of the lower ply, G, of the hem D stiffens and strengthens (No model.)

the said hem, and prevents the board from being twisted, warped, or drawn out of shape while being handled and displayed for sale, so that it will lie smoothly upon the floor. To the under side of the middle part or body of the plate A is secured, by paste or other cement, a veneer, E, or thin plate of wood.

In making the stove-board the bead B is so formed that the veneer E and the corrugated lower ply, O, of the hem D may rest smoothly upon the floor.

If desired, beads F may be formed around the center of the plate A, as shown in Figs. 1 and 2. By this construction a neat, ornamental, and serviceable stove-board is produced, which will not be drawn out of shape by use.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- A stove-board constructed, substantially as herein shown and described, of the zinc plate A, with a bead, B, and a hem, D, and having the lower ply, (J, of the hem D corrugated and its edge turned up against the plate A within the cavity of the bead B, and the ve neer E, cemented to the lower side of the plate A, as set forth.
